The shoe sole structure is resilient throughout the full length of its under surface, having a toe portion forwardly of the metatarsal arch region which is easily bendable, but having a relatively stiff and rigid upper surface from the metatarsal region rearwardly to the heel. The sole structure has an and elevated central pedestal under the instep region and a separate impact pad underneath the heel. In a running action the heel impact absorbs an initial impact with the ground the central pedestal then provides a rolling support for the entire foot, and finally the bending of the toe portion of the sole structure provides an effective and well- controlled take-off.
